That’s probably why some places sell the same exact tire with the same exact size/thread/rating have different prices…
I use to see some tires advertising an 80,000 mile tires. I thought this was ironic, because several most people think….”cool, I can keep my tires for 8+ years” I never keep my tires longer than 2-3 years tops. (thread usually goes faster for me)…And i check the manufacturing date too.
